Cops and Pollen

I recently drove to Albuquerque, New Mexico to discuss automated pollen sensing with their city air-quality folks. Google maps was helping me get there, when I heard a voice coming from my phone telling me there was a speed trap ahead. Wow. I don't have a lead foot, but it was a nice reminder to check my speed and make sure I wasn't at risk for a ticket. As the cursor on the highway got nearer to the place where the speed trap was supposed to be, sure enough: a state trooper lay in ambush!…

CSTE 2019 Abstract

Allergic respiratory disease places an increasingly large burden on public health systems as its prevalence within the U.S. population and worldwide has steadily increased over the past few decades. Contributing to the increases are elevated personal exposures to aeroallergens as plants respond to extended growing seasons and increased levels of carbon dioxide by producing more pollen with elevated allergenicity. Despite the importance of personal exposure to aeroallergens, there is no coordinated network that can provide aeroallergen data on geographical or temporal scales meaningful to individuals so they can make decisions to decrease their personal exposure.…

In Search of Pollen One of my favorite pollen excursions was when I went in search of mountain cedar trees in Northern Arkansas. Before I tell the story, let give you some insider information: Mountain cedar trees release pollen (pollinate) in December and January and are a big allergy/asthma/health problem in Southern Oklahoma, Dallas, and The Hill Country of Texas. The trees are in little pockets in Northern Arkansas but this is not well known and they aren’t considered much of a problem for allergy sufferers in that region because there are so few of…

Check Your Surfaces

Tedious Field Work When I was studying pollen at the University of Tulsa (go Golden Hurricane!) one of my tasks was to estimate the amount of pollen produced in a mountain cedar forest. To do that, you must first know that mountain cedars are dioecious, meaning that there are male trees and female trees. Since the male flowers produce the pollen, you need to estimate how many male trees there are in a given area. Then you have to estimate the number of male flowers on an average tree (in this case, the flowers are…
